Why doesn't Du talk about entanglement?

Du's entanglement theory has not been ignored. Du Fu's entanglement theory is a central theory named after himself, which comes from the entanglement theory of Zen and is classified into many courses after its own processing and understanding. If Du no longer teaches entanglement theory, there may be two reasons:

1. The small number of students and poor attention may have affected his income and popularity.

2. The loss and criticism of investors may make him be questioned and resisted, further prompting him to stop teaching entanglement theory.
